Hi all, Can someone please explain me how to use REG_SEQUENCE in tablegen? The arch i'm writing backend for has 32-bit regs, and it has a couple of 64-bit load/store instructions which use two neighboring regs at once, which i'm trying to employ using virtual regs with subs. For example, it I want to move one 64-bit virtual reg to another, I'm trying to use the following pattern:

Big thanks, i've managed to find what's going on. The thing that dumbfolded me a couple of times was that the error was thrown in one of the MCAssembler methods, but never in applyFixup() itself.

Mark, did you get anywhere with this? We have a similar issue, where a family of otherwise-identical instructions operates on different register classes depending on a non-static property -- functional unit selection in our case. I started to head down the path of using multidefs but quickly abandoned that. I had envisioned a MachineOperand that would hold the functional unit assignment, and

Hi all, I'm trying to make an LLVM backend for the Adapteva's Epiphany E16 CPU (used in Parallella board), using CPU0 and some other backends as examples, and I've got stuck with branching. When I'm printing out asm, all branch labels are printed as they should be. But when I'm trying to generate obj file, I'm getting zeros instead of PC-related offset in all branch

Hi. I am trying to install a package called DMwR http://cran.r-project.org/web/packages/DMwR/index.html located here: http://cran.r-project.org/bin/windows/contrib/r-release/DMwR_0.2.1.zip on windows 7.
